Corthe Dermo Bright C Ampul

The niacinamide and vitamin C combo has been a game changer for my uneven tone—my skin looks noticeably brighter after about three weeks. The ampoule texture sinks in fast and hasn't caused any irritation, which is a win for my sensitive face.

Two weeks in and the dark spots on my cheeks are visibly lighter, which is more than I expected from a niacinamide and vitamin C combo. It layers nicely under moisturizer without pilling, and my skin looks noticeably more even in the morning.

I’ve been using this every night for about three weeks and the dark spot on my cheek is noticeably lighter already, which I honestly didn’t expect so soon. The niacinamide and vitamin C combo feels gentle too—no stinging, just a light texture that sinks in fast before my moisturizer.
